ROBERT OSCAR JONES, OF PEORIA, ILLINOIS, ASSIGrNOR OF ONE-HALF TO ALICE GALLIYAN, OF IVESDALE, ILLINOIS.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 689,548, dated December 24, 1901. Application filed January 28, 1901. Serial No. 44,972. (No model.)

To LZZ whom t may concern.-

Be it known that I, ROBERT OSCAR JONES, a lcitizen of the UnitedStates, and a resident of Peoria, county of Peoria, andState of Illinois, have invented certain new and useful Improvements in Fire-Extinguishers,of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This inventionrela'tes to improvements in nre-extinguishing apparatus.

The natureand obj ect of the invention will be fully understood from the following general description and the annexed drawings and will be subsequently pointed out in the claim.

Figure l illustrates a common fire-ladder Wagon with my'newly-invented fire-extinguisher attached. Fig. 2 is a sectional view of my fire-extinguisheataken on the line y y of Fig. 4. Fig. 3 is a sectional view of the Fig. 4E is an end view of the same. Figs. 5 and 6 are detail views of the mechanism hereinafter more fully described.

The ladder-wagon A may be of any approved and adaptable form. On the top of the frame of this wagon are mounted two or more hose-reels B B, wound with lire-hose adapted with unions and couplings to work with the remainder of the apparatus, more fully hereinafter described.

Upon the ladder-wagon between the footboard F and the bottom of the bed-frame are mounted two or more stout hollow cylinders, (designated, respectively, by I and I.) These cylinders are preferably made of metal and of such strength as to resist very considerable pressure from within. Each cylinder is provided Witha hand-hole f, covered bya lid f which may be detachably fastened with clamps or screw-bolts or in any otherA secure and convenient way. A shaft M is j ournaled on the inside center of the head K of the cylinderI. Thisshaftextendsthroughthewhole length of the cylinder and alittle beyond its other head. Upon this shaft within the cylinder are mounted the spokes m, and upon these the vanes m', m2, m3, and m4. These vanos are arranged and adapted to revolve with the shaft M very near to the internal surface of the cylinder. Upon this same shaft, sustained by the vane m2 and detachably attached to the end thereof, as more fully hereinafter described, is mounted the acidcup H. This cup may be made of any acidproof materialsuch as glass, chinaware, earthenware, and the like. a lid H', adapted to easily fall off when the vcup is inverted.. The shaft M is revolved by the hand-crank 1l, which is'xed on its Yprojeoting end outside of the cylinder. vent the escape of any of the contents'of the cylinder around the shaft M, a stuffing-box I2 is provided, Vwhichmay be set up so fast as vto prevent such escape.

-in any adaptable and secure way. On the outer end of this is a hinget, by which it is pivotally fastened-to the other part of the strap, the two parts together forming a yoke or loop adapted to embrace the acid-cup H a little above its middle and above the strap The inner end of this last-named part of the upper strap h is attached to the vane m2 by the yoke h2, on which works the button h3. This button h3 is constructed and arranged so that when it is in the position illustrated in Fig. 5 it will bind the yoke end of the strap h to the vane m2; but when it is turned to a position at right angles to 'this the end of the strap will be free to be drawn away from thevane, swinging around on the hinge k2. When the straps h and `h are in the position illustrated in Fig. 5, the acidcup will be held in position; but when the upper strap is opened, as above described, the acid-cup can be readily lifted out of its support to be refilled or replaced by another, as may be required.

To prevent the crank t and the shaft M from turning when it is not desirable, a stop is provided. This stop engages the groove I3 To prey It is fitted with IOO in the head of the cylinder. A short shaft 3, having the head 4 and the jaws e2, is adapted to slide a little in the boss e on the crank i. The helical spring i?, embracing the shaft i3 between the boss e and the head 4, holds the head t4 normally in locked position in engagement with the groove I3; but when it is desired to turn the crank the cam-lever 2 is turned to a position opposite from that which it occupies in Fig. 6. This will lift the head i4 from out of engagement with the groove I3, and the crank will be free to be turned with its accompanying mechanism.

The two cylinders I and I', which are both constructed in the same way and with the same internal mechanism, are connected by the branch tubes d and d with the upright pipe D. This pipe D extends through alittle more than the whole height of the ladderwagon body and is provided at top and bottom with union-sections e and cl2, respectively. Near the bottom of the pipe D is a Valve b2. Between the cylinders in the branch tubes d and d are placed the valves b and b', the whole device to be substantially as herein illustrated and described.

To use my invention, the cylinders are' charged through the hand-holes f with an alkaline solution, preferablyasaturated solution of a salt of soda in water. A little more of the salt than the water will dissolve may be put in the cylinder. The cup H, which is to be placed in the position illustrated in Fig. 3, is then to be lled with acid in suiicient quantity to neutralize the alkali inthe cylinder. For this purpose many diiferent acids may be used; but I prefer to use sulfuric acid. The lid I-I' is then placed on the cup 1I, the hand-hole cover f fastened on the hand-hole f, and the crank t locked, as before described. The apparatus will then be in proper condition for use. As soon as the apparatus has arrived at a re a sufficient length of hose is unrolled from the hose-reels B B. rIhe hose is then attached by the union e3 to either the union-section e of the unionsection d2 or different lengths of hose may be attached to each union-section. Then if it be desired first to use the cylinder I the crank t' is unlocked, as before described, and turned rapidly several times. This inverts the cup II. The top I-I falls off. The acid pours into the alkalic solution and by the motion of the Vanes is thoroughly mixed therein. generation of gas a considerable pressure in the inside of the cylinder. If then the valve b be opened, the iluid contents of the cylinder will rush through the pipe D into the hose and may be used for extinguishing a re in the common and well-known way. The cylinder I, if required, may be utilized in the same way. The cock b2 is primarily intended to be a blow-od cock; but if it be required a hose may be attached to the union-section d2 and the contents of the cylinder conducted to the lire that way also.

This in practice will he found a very economical, adaptable, and convenient apparatus for extinguishing small tires, such as occur in villages and other places where the houses are comparatively far apart.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a fire-ladder Wagon; hose-reels mounted thereon, foot-boards mounted thereon; and hollow cylinders, closed at both ends mounted on said footboards; of shafts journaled in said cylinders, spokes on said shafts, within said cylinders, stirring-varies on said spokes; acid-cups mounted on the ends of said stirring-vanes, within said cylinders; one rigid strap detachably attaching each acid-cup to its adjacent Vane; and one strap embodying a hinge and a yoke, and in combination with said rigid strap, detachably attaching each acid-cup to its accompanying vane; buttons Working in said yokes, to effect such attachment; cranks for turning said shafts; means for holding them in position; means forcharging said cylinders, t'or connecting them together, and for connecting them with hre-hose; all substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 26th day of December, A. D. 1900.
